to be emitted from the Sun. This limit pertains equally to electric dipole and magnetic
transition moments, and it applies to both Dirac and Majorana neutrinos.
51 ACCIARRI 97Q result applies to both direct and transition magnetic moments and for
q2 =0.
52 ELMFORS 97 calculate the rate of depolarization in a plasma for neutrinos with a magnetic
moment and use the constraints from a big-bang nucleosynthesis on additional
degrees of freedom.
53 Applies to absolute value of magnetic moment.
54 COOPER-SARKAR 92 assume fDs /fπ =2andDs ,Dsproduction cross section =
2.6 µb tocalculateνflux.
55 KAWANO 92 lower limit is that needed to circumvent 4He production if mν is between
5and∼30 MeV/c2 .
56 RAFFELT 90 limit valid if mν < 5 keV. It applies for a diagonal magnetic moment of
a Dirac neutrino, or for a transition magnetic moment of a Majorana neutrino. In the
latter case, the same analysis gives < 1.4×10−12 . Limit at 95%CL obtained from δMc .
57 Significant dependence on details of stellar properties.
58 GROTCH 88 combined data from MAC, ASP, CELLO, and Mark J.
59 If mν < 10 keV.
60 For mν = 8–200 eV. NUSSINOV 87 examines transition magnetic moments for ντ →
νe and obtain < 3 × 10−15 for mν < 16 eV and < 6 × 10−14 for mν > 4eV.
